linux下cocos2d-x 2.2.1编译过程中的问题

1.编译过程中 将warnning 认定为error，修改方法试了很多种

      1)find . -name 'Application.mk' |xargs sed -i '1i APP_CPPFLAGS += -Wno-error=format-security'  #在所有Application.mk文件中添加一句话APP_CPPFLAGS += -Wno-error=format-security，这个是在很多国外网站上看到的，但实际还是报错，出错原因是把 unsigned int 转化成了 long unsigned int，%ui --> %lu  ，把相应文件的 lu全部改为ui后编译顺利通过

2.编译helloCpp的时候出错，大致为：

Using auto-detected project path: .
Found package name: org.cocos2dx.hellocpp
jni/Android.mk:19: *** Android NDK: Aborting.    。 停止。
ABIs targetted by application: Android NDK: WARNING: Ignoring unknown import directory: /home/wyl/work/tools/cocos2d-x/cocos2d-x-3.0alpha1/cocos/cocos2dx/platform/third_party/android/prebuilt    
Android NDK: jni/Android.mk: Cannot find module with tag 'cocos2dx' in import path

ERROR: The device does not support the application's targetted CPU ABIs!
       Device supports:  armeabi-v7a armeabi
       Package supports: Android NDK: WARNING: Ignoring unknown import directory: /home/wyl/work/tools/cocos2d-x/cocos2d-x-3.0alpha1/cocos/cocos2dx/platform/third_party/android/prebuilt

解决方法：export COCOS2DX_ROOT=/home/wyl/work/tools/cocos2d-x/cocos2d-x-2.2.1  路径设置出错，之前用的3.0 alpha，还有许多bug未修复，改成2.2后编译通过

3.继续编译还是出错：

ERROR: Package org.cocos2dx.hellocpp is not debuggable ! You can fix that in two ways:

  - Rebuilt with the NDK_DEBUG=1 option when calling 'ndk-build'.

  - Modify your manifest to set android:debuggable attribute to "true",
    then rebuild normally.

After one of these, re-install to the device!

解决方法：在Androidmanifest.xml中添加   android:debuggable="true"

          <application android:label="@string/app_name"
                 android:debuggable="true"
                 android:icon="@drawable/icon">

4.继续出错：

Found debuggable flag: true
ERROR: Could not find gdbserver binary under ./libs/armeabi
       This usually means you modified your AndroidManifest.xml to set
       the android:debuggable flag to 'true' but did not rebuild the
       native binaries. Please call 'ndk-build' to do so,
       *then* re-install to the device!

5.ndk 编译出错：

   undefined reference to `__gnu_thumb1_case_si 更换为r9后ok

6.将“adb_var_shell2 DATA_DIR run-as $PACKAGE_NAME /system/bin/sh -c pwd”用DATA_DIR="/data/data/$PACKAGE_NAME" 替换
